联合垂直地震剖面资料提高地面地震资料分辨率的应用研究
Application of improving surface seismic resolution using vertical-seismic-profile data
摘要
Abstract
The theory and method of quality factor (Q) estimation using P-wave first break in three-component vertical-seismic-profile (VSP) seismic data, stabilized inverse Q-filtering method were given and a processing flow for improving surface seismic data resolution combined with VSP seismic data was proposed. The elastic parameters can be derived from three-component VSP seismic dataset, such as velocity ratio of P-and S-wave, Poisson's ratio and volume modulus. These parameters can be used to correct the Q model estimated from VSP seismic data. The results of real field VSP seismic data and seismic data across the well show that the methods and technique process are feasible. It can enhance the seismic resolution without effects on the seismic signal-to-noise ratio. Compared with the stacked VSP seismic trace to the seismic sections before and after inverse Q filtering, the seismic data with high resolution agrees well with the VSP results.关键词
